In addition, when the cover 20 is covered on the case 10, the explosion-proof heat-dissipation charging protector 1 of the present invention is closed, and when the concentration of carbon dioxide inside the protector reaches a certain degree, the fire can be extinguished perfectly.

According to the design of the present invention, the steel cylinder of the fire-fighting part 401 of the explosion-proof heat-dissipation charging protector 1 is a small-sized high-pressure steel cylinder, and the fuse 403 is sealed to prevent gas from leaking, so that when the fire is ignited and burned in the accommodating groove 105, the fuse 403 is fused, and the fire-extinguishing gas can be sprayed into the accommodating groove 105 to extinguish the fire. The installation mode of the high-pressure steel cylinder is as follows: when the high-pressure steel cylinder is mounted, firstly, the fuse 403 is sealed and filled, then the pipeline 407 is rotated upwards, then the high-pressure steel cylinder is sleeved on the joint of the pipeline 407 and screwed, then the pipeline 407 and the high-pressure steel cylinder are rotated together downwards to the box body 10, and finally the high-pressure steel cylinder is buckled in the clamping groove; the fuse 403 is installed in the following manner: a through hole (not shown) is formed in the fire-proof layer 103, an opening at one end of the pipeline 407 is inserted into the accommodating groove 105 through the through hole, and the fuse 403 is fastened to close the opening at one end of the pipeline 407.

Wherein, the cooling liquid comprises at least one of pure water, monoethylene glycol, diethylene glycol and propylene glycol or a combination thereof, and the most preferable fire extinguishing agent for metal disaster prevention is sodium chloride dry powder. Due to the non-conductive nature of the cooling fluid, there is no danger of an electric shock when it is hit by the cooling fluid, even if the power supply of the electronic device 30 within the housing 10 is continuously charged.
